About this conversion
Converting JSON to Excel turns API responses, database exports, and structured data files into a spreadsheet any business user can open, filter, and analyse without technical tools. The JSON array of objects becomes a table where column headers come from the JSON keys and each array element is a row, ready to sort, pivot, and format in Excel or Google Sheets.
Common use cases include turning a REST API response into a shareable report, converting a Stripe or Shopify data export for a finance team, transforming a configuration or catalogue file into a spreadsheet for review, and exporting analytics event data for a business stakeholder. XLSX handles special characters and long text values more reliably than CSV for distribution to end users.
If your JSON contains nested objects or arrays, those fields are serialised as JSON strings in the Excel cells. For a cleaner result with flat columns, run the Flatten JSON tool on your file before converting to Excel — nested keys become dot-notation column headers that map cleanly to individual Excel columns.
Frequently Asked Questions
What is Excel format?
Excel (XLSX) is Microsoft's spreadsheet format, widely used in business. It supports multiple sheets, formulas, and formatting.
Is my JSON data private?
Yes — completely. Your file is never uploaded to any server. All conversion happens inside your browser using WebAssembly — locally, with no upload. Once you close the tab, nothing is retained.
What is the maximum file size?
The free limit is 50 MB. For larger files, performance depends on your device's available memory — most modern machines can handle 500 MB to 1 GB comfortably.
What is the difference between JSON and Excel?
JSON is lightweight and ideal for APIs and programmatic use. Excel is better for sharing with business users who need to view, filter, and format data in a spreadsheet.
